Evening guys.
Got a problem with one of my auto's I'm growing. The bitch doesn't want to go in to flower properly.
I'm growing 2 auto's. Both are the same age and same strain. Dutch passion BlackBerry
All went well until a couple of weeks ago when I started seeing light coloured leaves on the sick girl.
It looks a bit like magnesium but it can't be that because I have been giving a little extra mag from the start.
Can't be light burn because she got it when she was smaller the the other girl. That one looks perfectly fine.
She had a slight cal problem before but I fixed that by giving extra cal (canna mono cal)
She has been given the same food as the healthy girl so it can't be a ph issue because the other girl is perfectly fine.
Furthermore she got a much thinner stem than the other one. Even the branches are a lot thinner.
Only thing that could explain it from looking online is a copper deficiency. But I'm not sure of it and haven't got a clue on how to fix it.
I included some pictures. The first 2 are from the sick girl. The last is from the healthy one.
Currently feeding them 2ml/L Canna a&b + a bit of cal and some fulvic acid to bring total ec to 1.2 (0.1 background)
Any advise on this anybody?
cheers
